聚醚酰亚胺聚合物

产品详细信息

聚醚酰亚胺（PEI）是一种无定形的琥珀色透明热塑性塑料，其性能与相关塑料PEEK相似。与PEEK相比，PEI更便宜，但冲击强度和可用温度更低

聚醚酰亚胺（PEI）是一种超级工程塑料，由无定形聚醚酰亚胺、琥珀色透明固体制成，与其他芳香族聚酰亚胺相比，它是一种成本更低、产量更高的热塑性聚酰亚胺

性能特征

1。物理性质：非结晶；尺寸稳定性好；蠕变敏感性低；热膨胀系数小且均匀；优异的强度重量比；很好的着色性；符合FDA和NSF标准。耐热性能：高温稳定性；很高的长期耐热性，热偏转温度220℃；玻璃化转变温度（Tg）为217℃，HDT/Ae为190℃，可在-160 a 180℃的工作温度下长时间使用，允许间歇最高使用温度为200℃；导热系数为0.22 W/m/K。电性能：优异的电性能；在较宽的频率和温度范围内，具有稳定的介电常数（低至3.15）、介电损耗和极高的介电强度；电气绝缘

耐候性

PEI具有优异的耐候性，在不使用任何稳定剂的情况下可承受紫外线照射。在氙灯风化室中暴露1000小时后，抗拉强度变化非常小。β射线下的抗辐射性也优于PSF、PES等。

抗辐射性

PEI还表现出良好的抗伽马辐射能力，以每小时1兆拉德的速率累积暴露在钴60中5000兆拉德后，抗拉强度仅损失6%。此外，PEI对可见光、红外和微波都有透射性，不吸收

成型加工性

与热固性聚酰亚胺不同，PEI可以通过传统的热塑性成型方法进行加工，并且具有完美的机械切割和二次装饰性能，可以制造各种各样的零件

Polyetherimide Polymer

Polyetherimide Polymer
Polyetherimide, abbreviated as PEI,
is an amber colored transparent solid,
flame retardant V-0 grade,
with a density of 1.28~1.42g/cm3.
PEI has a strong high temperature stability.

Polyetherimide Polymer

Product Details

Polyetherimide (PEI) is an amorphous, amber to clear thermoplastic with properties similar to the related plastic PEEK. Compared to PEEK, PEI is cheaper, but has lower impact strength and usable temperature.

Polyetherimide (PEI) is a super engineering plastic made from amorphous polyetherimide, an amber transparent solid, and a lower cost, higher yield thermoplastic polyimide compared to other aromatic polyimides.

Performance characteristics.

1. physical properties: non-crystalline; good dimensional stability; low creep sensitivity; small and uniform coefficient of thermal expansion; excellent strength-to-weight ratio; very good coloring resistance; FDA and NSF compliant

2. Heat resistance performance: high temperature stability; very high long-term heat resistance, heat deflection temperature of 220 ℃; glass transition temperature (Tg) of 217 ℃, HDT / Ae 190 ℃, can be used for a long time at -160 a 180 ℃ working temperature, allowing intermittent maximum use temperature of 200 ℃; thermal conductivity of 0.22 W / m / K

6. electrical properties: outstanding electrical properties; stable dielectric constant (down to 3.15) and dielectric loss and very high dielectric strength in a wide range of frequencies and temperatures; electrical insulation.

Weathering resistance.

PEI has excellent weathering resistance and can withstand UV exposure without any stabilizer. After 1000 hours of exposure in a xenon lamp weathering chamber, the tensile strength changes very little. The radiation resistance under beta ray is also better than PSF, PES, etc.

Radiation resistance.

PEI also shows good resistance to gamma radiation, with only 6% loss in tensile strength after cumulative exposure to cobalt 60 at a rate of 1 megarad per hour for 5000 megarads. In addition, PEI is transmissive to visible light, infrared and microwave and does not absorb.

Molding processability.

Unlike thermoset polyimide, PEI can be processed by conventional thermoplastic molding methods, and with perfect mechanical cutting and secondary decorative properties, a wide variety of parts can be manufactured.
